Abstract

A novel post-processing technique in the DCT domain, based on the theory of the projection onto convex sets (POCS), to reduce the blocking artifacts in the block discrete cosine transform (BDCT)-coded images, is proposed. Computer simulation results indicate that the proposed scheme performs better than conventional post-processing algorithms. Furthermore, the proposed algorithm can be implemented without DCT/IDCT operations. Estimates of computation savings vary between 41 and 64% depending on the task.
